I tried to login using putty, and when I login as root, it hangs.
The only thing I can see on the screen is:

login as: root
Sent username "root"

The ping works, but nothing else does.

Any ideas?

Thank you,
Reyner

Sorry for the silly question, but are you using SSH or Telnet?

Oopss ... I forgot to mention it (sorry).

I'm using SSH.

I also got a lot of this for some reason:

I'm also using php 4.1.2.

You mean HTTP, FTP, .. etc doesn't work?
They used to work or this is a newly configured system?

Also, try loggin in as another user, other than root and see if it works. If you can login as anybody else, you can use 'su -' to become root.

You mean HTTP, FTP, .. etc doesn't work? Yes, nothing else work, just the ping. Everything works just fine after I reboot it, but this happens twice already.

I've looked at the apache logs, but it doesn't show anything really weird. I was hoping if someone had this kind of experience before and could shed some englightment.

Weird ... weird problem (which maybe caused by a little things, but who knows ...) :)

Still looking for answers,
:)

Check in /var/logs/message for any error before reboot the server

Well, I've checked most of the messages. Some of them I know, but some are not quite familiar. Is there a good reference to learn more about error logs?

Post em' here :D...

And a good reference... google man google... It knows all...

Probably a resource exhaustion problem. Try actively monitoring the server by watching 'top' output. If you see a process consuming a lot of resources (CPU, memory) try killing it immediately. Put an rlimit around it, and the o/s will take care of killing it should it happen again.

Thank you all for posting. The problem seems to be a conflicting cron job that took all the resources and freeze the server :)
